Diode Dynamics D-Switch Hubs

Take your vehicle's setup to the next level with the Diode Dynamics D-Switch hubs. These advanced 8-channel switch panels give you full, customized control over any 12 V accessory that you want to wire up. They replace traditional, fixed-switch panels with customizable, app-controlled, or physical switching, enabling multiple outputs, strobe patterns, and high-current management in a rugged, IP67-rated unit. Key features and benefits: * Extreme durability—the hub features a fully encapsulated design with a cast aluminum heat sink, making it IP67-rated for water and dust resistance, essential for harsh off-road environments * Solid-State reliability—with no mechanical relays to fail or fuses to replace, the solid-state design improves longevity and performance. * Customization and flexibility—users can program different behaviors for the same light (e.g., one button for full power, another for strobe) * Intelligent features—Night Mode for automatic backlighting adjustment and allows for setting up complex scenarios for accessories * Centralized control—allows users to consolidate power management for up to eight separate 12 V accessories (e.g., lights, air compressors, fans) into one system, reducing under-dash wiring clutter * Dynamic channel assignment—the D-Switch is not hard-wired (1-to-1); any button can control any combination of outputs, allowing users to group multiple devices (e.g., ditch lights + bar + rock lights) to one button * App-Based customization—a Bluetooth app enables users to name channels, customize button icons, set strobe patterns, dim lighting, and monitor total power draw * Advanced features include specialized functions like dedicated backlight control, integration with factory trigger wires, and strobe/flash options for lighting, perfect for chase lights * Easy installation—includes necessary wiring, a swiveling mount for the 8-button panel, and a 3-year manufacturer warranty for peace of mind

MSD Ultra 6AL Ignition Boxes

The new Ultra 6AL Series ignition boxes deliver full MSD power in a compact, lighter package! The Ultra 6AL Series continues to use a high-speed controller that can make extremely quick compensations to the output voltage, multiple spark series, timing and rpm limits, while maintaining precise timing and accurate rev limiting. The circuits and controller of the MSD have been thoroughly filtered to create protection against Electro Magnetic Interference (EMI). Ultra 6AL Series features a capacitive discharge ignition design. (The majority of stock ignition systems are inductive ignitions, in which the coil must store and step up the voltage to maximum strength in between each firing. At higher RPM, since there's less time to charge the coil to full capacity, the voltage falls short of reaching maximum energy—which results in a loss of power or top end miss.) MSD Ultra 6AL ignition box details: * High conversion efficiency ensures minimal heat generation and maximum spark energy output with less current draw from the battery * High RPM operation and maximum output using the Blaster HVC, PN 8252 or HVC II, PN 8253 * Powerful capacitive discharge of multiple sparks improves performance * Consistently high spark energy of 135mJ to 150mJ for every firing, from idle to redline RPM * Increase spark series duration lasts for 18 of crankshaft rotation * Easily installs on 4, 6, 8-cylinder engines with distributors * Operates on most 7 to 28 volt electrical systems * Connects to points, magnetic pickups, and hall/crank input distributors * Bluetooth connectivity to mobile app interface for settings and monitors * MSD CAN communication for easy connectivity to MSDView using a CAN MSD Hub and Power Grid USB or CAN-USB Bridge 89982 product * Fully protected against an open coil, shorted coil and open load * Compact design full MSD power * Quickens throttle response and improves starting * Tach Output * Launch, Burnout, and Step Retard activation inputs available.

Dorman ABS Speed Sensors

Dorman ABS speed sensors are designed to supply information regarding wheel speed to the ABS computer. One of the most common omissions in maintaining a modern anti-lock brake system (ABS) is checking out the speed sensors. They are often located at each wheel hub/rotor on 4-wheel disc systems. Alternatively, on rear drum applications, you'll usually find them mounted on the differential housing. Under braking, if wheel speeds are unequal, indicating wheel lockup, the computer modulates the anti-lock feature until the speeds are equal again.
